Just throwing my experience in here:
I installed latest Debian stable (12.4) and this suspend behavior seemed to be my only issue.
I upgraded to Trixie (testing), and suspend works fine now.
I still get an error when running the above script:
🚦 AMDGPU firmware is missing
The amdgpu driver loads firmware from /lib/firmware/amdgpu
In some cases missing firmware will prevent a successful suspend cycle.
Upgrade to a newer snapshot at https://gitlab.com/kernel-firmware/linux-firmware
amdgpu 0000:c1:00.0: Direct firmware load for amdgpu/gc_11_0_1_mes_2.bin failed with error -2
For more information on this failure see:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1053856
Even though the suspend seems to work fine.
I also still get all the above warnings when generating an initramfs, despite suspend working.
Maybe I’ll find that something else is broken, but I’m happy with trixie for now.
